SPECIFICATION foriingppart 0f Letters Patent N0. 7 29,425, dated. May' 26, 1903 Application filed February 14, 1903. Serial Nall/3,431. (No model.)

.To all whom t may concern;

Beit known that I, DOMINIVC F. SCHULER, a citizen of the United States, residing at Louisville, in the county of Jetferson'and State of Kentucky, have invented anew and useful 4Boiler-Cleaner, of which the following is a specification.

This invention relates to a blow off or cleaner .for liquid-containing 'vessels especially designed for use in connection with steam-boilers, and has for its object to provide asimple, inexpensive, and efficient device of this character for removing dir t, scales, and other sedimentary deposits which usually accumulate in steam-boilers after being in use for any length of time, causing incrustation and otherwise seriously impairing the strength of the same.

A further object is to provide a cleaner the relative disposition of the several parts being such as to permit its being easily introduced into and removed from the boiler, the cleaning-openings being arranged on the under side of the washout-pipe and disposed transversely thereto, thereby preventing the sedimentary deposits from clogging said openl ings and also causing the sediment when the blow-01T valve is opened to be sucked downwardly from the sides of the boiler and upwardly from the bottom thereof, effectively cleaning the same throughout its ent-ire length.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changesi'n form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a longitudinal section of a boiler, showing my improved blow-od or cleaner applied thereto; and Fig.- 2 is a transverse section on the line 2 2 of Fig. 1.

Similar numerals of reference indicate corresponding parts in both figures of the drawlngs.

Y 1 designates the boiler, which may be of the usual form and construction, and 2 the blow-off or cleaner.

The boiler 1 is provided with an opening or orifice 3,`having a reinforcing-flange 4, secured inY any suitable manner to the walls of the boiler, as by means of rivets or bolts 4 or similar fastening devices, and this flange is providedwith an upwardly-projecting internally-threaded collar 5', adapted to receive the correspondingly-threaded end of a pipe 6, whichpasses through the orifice 3 and eX- Vtends withimthe boiler. .The lower threaded end 7 ofthe pipe 6 engages :aT-shaped coupling-8.having a pair of longitudinally-disposedwashout-pipes 9 threaded in the opposite ends thereof and which supports said pipes aslight distan-ce above the bottom of the boiler, as clearly shown in Fig. 1 of the drawings. The pipes 9 lie parallel with the bottom ofthe boiler and extend, respectively, in opposite directions to a point adjacent the heads'pofj'the boiler, the ends of the pipes being provided with caps 10, having one or more angularly-disposed openings l0. The pipes 9 are provided on the under side thereof witha series of segmental slots or openings 11arranged in longitudinal alinement and extending transversely across the bottom of the'pipes and approximately half-way up the side y thereof and through which the dirt and othersedimentary deposits are removed when the boiler is cleaned. A blow-off valve 13, provided with a handle 14, is threaded on the upper end of the pipe 6, and connected to thevalve 13 is a discharge-pipe 2, which communicates with a sewer or other suitable discharge.-

From the foregoing description the operation of my device will be readily understood and is as follows: In placing thecleaner in position the T-shaped'coupling carrying the washout-pipes is inserted in the boiler through the usual end manhole.L The piped, having the valve 13 secured.thereto,is vthen introduced through the orifice 3 and the parts assembled by screwing the pipe 6 into the T- coupling, thus securing the sections together. Any sedimentary deposits accumulated in the boiler may new be removed by turning the IOO valve 13, the pressure of steam within the boiler causing the sediment to be sucked throughthe openings in the pipes 9 and through the pipe 6 and valve 13 to any suitable discharge-as, for instance, a sewermain.

The washout-pipes are of approximately equal length and normally lie parallel with and supported slightly above the bottom of the boiler, so that when the blow-01T valve is opened the suction caused by the inrushing steam and sediment will have a tendency to draw the ends of the Washout-pipes'downwardly, facilitating the removal of any accumulated deposits at the juncture of the head and side walls of the boiler, the washoutpipes assuming their normal position as soon as the valve is closed.

By having the cleaner made in several sections, as described, it not only permits the same to be inserted in and removed from the boiler with ease and despatch, but also permits any one of the sections being removed and replaced when corroded or otherwise worn by the action of the Water.

By having the openings arranged in the under side of the pipe the sediment is prevented from obstructing the same, and when the valve is opened the pressure of the steam will cause a direct suction on the sides as well as the bottom of the boiler, thereby eectively removing all sedimentary deposits.

Having thus described my invention, what I claim, and desire to secure by Letters Pat ent, is-

1. A blow-oli. or cleaner for boilers, comprisinga discharge-pipe, a longitudinally-disposed tube secured to the discharge-pipe and supported above the bottom of the boiler, said tube being provided with a series of transversely-disposed segmental inlet-openings, a cap provided with angularly-disposed openings secured to the opposite ends of the'tube, and a valve for regulating the discharge from the boiler.

2. A blow-011:' or cleaner for boilers, comprising a discharge-pipe, a T-shaped coupling connected to the discharge-pipe, a pair of oppositelyextending longitudinallydisposed tubes supported above the bottom of the boiler and detachably connected to the T- coupling, said tubes extending the entire length of the boiler and being provided with a pluralityof transverselydsposed segmental inlet-openings, caps secured to the free ends of the tubes and provided with angularlydisposed openings, and a valve for regulating,r the discharge from the boiler.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

DOMINIO F. SCHULER.
